4.2 Description
The 2-finger parallel gripper is a servo-electric gripping module
with integrated control and regulating electronics.
The 2-finger parallel gripper is designed to be attached to a LWA
4P or LAW 4D lightweight arm.
The defined mechanical and electrical interface also makes it pos-
sible to attach it to other commercially available industrial and
lightweight arms.
Attaching it to a lightweight arm or to another application is carried
out via the SCHUNK flat change system FWS115

The 2-finger parallel gripper is suitable for mobile applications due
to its design and low energy consumption.
A brushless DC servomotor drives both of the gripper base jaws.
An integrated permanent magnet brake for holding the position of
the drive blocks the motor shaft when actuated by the motor con-
trol accordingly and when the supply voltage is switched off (the
brake is not approved for holding workpieces). The position of the
gripper base jaws is constantly monitored using a sensor system.
In this way the distance between the gripper base jaws in relation
to one another is determined using internal referencing.
The complete control electronics is integrated in the 2-finger par-
allel gripper.
